The present invention discloses a method and system for snapshot-based online backup operations permitting reduced requirements to storage capacity and computational overhead for snapshot function.

At the beginning of an online backup operation, the backup software system creates a snapshot of source data storage. The snapshot includes a watch-list used for identifying blocks of a source storage which are watched by snapshot management means for update. If a block included into the watch-list was requested for update, the snapshot management means preserve original contents of that block in a retention container for the purpose of temporary store. The retention container includes a set of temporal stores dedicated for transient storing of blocks until they are backed up.

The essence of the invention is enabling to exclude blocks from the watch-list and the retention container at any moment within the period of snapshot operation. Therefore it is possible to exclude unnecessary blocks from the scope of blocks managed by the snapshot management means, for the purpose of preserving point-in-time data.

Backed up blocks can be operatively excluded from the snapshot so that unchanged blocks are excluded from the watch-list and updated blocks are removed from the retention container. In the latter case temporal stores are shrunk as well. This technique allows to reduce progressively storage expenses and computational overheads required for maintenance of a snapshot being used in the online backup routine.

When a volume-level online backup is performed the snapshot is switched to the read-once mode at the beginning of the data copying stage. A backup utility performs sequential read of blocks from the snapshot. The snapshot management means automatically exclude requested blocks from the scope of managed blocks.

A disk array connected to a storage area network via a fiber channel has one or more ports each controlled by a processor. Even the disk array with one port and one processor executes online processing and backup processing at the same time while considering an online processing load. A port controller not only accepts a request from a host computer but issues a request to other storage controllers to allow online processing and backup processing to be executed at the same time. In addition, the disk array, if provided with a plurality of ports, selects ports or schedules processing depending upon the load to prevent backup processing from affecting online processing performance.

The invention relates to a file online backup method. The traditional backup method is complex in operation and has low backup efficiency. The method disclosed by the invention comprises a file backup stage and a file recovery stage, wherein during backup, a user file is partitioned by a backup agent, and the sub-block data are sent to a storage server through a network. During recovery, the backup agent downloads the original backup data to the specified directory of a local host from the storage sever through the network. By the method, the backup is selected according to the type of the file, selective backup of the file of the specific type is realized, a multi-task backup mode is realized at the same time, and multiple folders can be independently backed up.

The present invention discloses an online backup method and system for a virtual machine. The method comprises: when a backup instruction is detected, opening up a cache space for the virtual machine, and determining whether a write operation for a virtual disk of the virtual machine exists; when determining that the write operation for the virtual disk exists, intercepting write data corresponding to the write operation, and storing the intercepted write data into the cache space; and backuping backup related data of the virtual machine in the virtual disk to a preset backup server. For the situation that the write operation for the virtual disk exactly exists at a moment for backuping the virtual machine, the write operation of the virtual machine does not need to be paused, but a storage space needed for services is provided by the pre-opened-up cache space instead of the virtual disk, so that the services of the virtual machine are smoothly conducted, user data is not lost, and the service performance of the virtual machine is improved.

The invention discloses a data compression method in on-line backup service software, belongs to the field of computer storage backup services and computer data compression and aims to improve the efficiency of the storage backup service. In the invention, the method for reducing the system load through a two-stage compression strategy at a client is provided. Upper compression is global compression which is used for blocking a backup original file according to a fixed size, calculating hash value of each block and taking the hash value as an identify of the data block so as to ensure that each data block has only one copy in the global scope of a storage end. Lower compression is of block level, which is used for realizing compression in the data block through a compression algorithm so as to reduce the data quantity needing to be transmitted through the network and save the bandwidth. The combined action of the two stages of compression not only improves the efficiency of the backup service, reduces the data transmission quantity and also improves the utilization ratio of the space at the storage end.
